Meet Khemmikka Na Songkhla, the world's foremost practitioner of the breast-slapping, a particularly vigorous alternative treatment that involves bosoms and a steady wrist.

The government-approved beautician has been practicing this form of aggressive massage for quite some time. In fact, the Thai Health Ministry launched what is probably the world's only study on breast-slapping after controversy developed over the safety of Khemmikka's practice several years ago. From The Independent:

[Her] lucrative business threatened to go bust after a client developed breast cancer and blamed it on her breast massage. Distraught, Ms Khemmikka asked the Health Ministry to learn if there could be a link with breast massage.

Dr Pennappa Sapcharoen, the deputy director of the traditional medicine division, told her no clinical trials had been done, but she was intrigued by the technique. The ministry launched a six-month study on volunteers aged 20 to 60, and found vigorous massage left their breasts cancer-free and measurably bigger.

Khemmikka charges 8-million Thai baht ($263,504) to teach the secrets of breast-slapping. On a related note, anyone in the comments offering to lead said courses for free will be sent to The Cornfield for "Crimes against Creativity." Similarly, anyone making a GIF of Khemmikka's groovy face-slap dance at 0:17 will be showered with adulation.
